how to find "r" if (r/4)^36 = .12244898
Take the 36th root of each side......remember that we must take the ± 36th root on the righr side !!!
So we have
r/4 = ± (.12244898)(1/36) multiply both sides by 4
r = ±4 (.12244898)(1/36)]
r = about ±3.77334
(r/4)^36 = .1244898
To remove the 36th power, take the 36th root. The 36th root is the power (1/36)
[ (r/4)^36 ] ^ (1/36) = (.1244898) ^ (1/36)
r/4 = (.1244898) ^ (1/36)
r = 4 x (.1244898) ^ (1/36)
r = 3.7733...
